Focus control trigger Autofocus, switchover immediately (synchronously)

Reading pulse source Start: "Sensor" switching input (active: high); end: "Sensor" switching input

"IN 0"to "IN 4" switching inputs Focus position changeover (without meaning for autofocus function)

"Sensor" switching input Start and end of reading pulse (level: active high), debouncing 20 to 30 ms

Switching outputs Not inverted; pulse duration: 100 ms

Status output function Result 1: Device Ready (static); Result 2: Good Read; Result 3: No Read; Result 4: Match 1

Reading data on No Read: output: yes, contents: Code Info/Separator and Error string

Error string: NOREAD

Output sorting In accordance with reading angle

Output time Read result: end of the read interval Code Info/Separator: after code

Test string Not activated

Auxiliary interface RS 232, 9 600 bd, 8 data bits, no parity, 1 stop bit (values cannot be changed)
